“I promised myself to never lose to clemson as a starting QB at South Carolina… NEVER,” he wrote. “They gone feel what they missed out on I promise y’all.”

Joyner had an offer from Clemson, but not to play quarterback. He committed to South Carolina over North Carolina State in June. He also had offers from Alabama, Oregon and Virginia Tech, among others.

The Tigers, of course, are coming off back-to-back national championship game appearances, including a win against Alabama last season. Clemson had no issues while handling South Carolina in Will Muschamp’s first season, a 56-7 win that was one of the most lopsided in series history.

Joyner, the 2016 South Carolina Gatorade Player of the Year, passed for 3,642 yards and 44 touchdowns last season. He rushed for 1,089 yards and 12 scores.
